No network connection with the GSM module

Hi all,

i'm having troubles getting the GSM module to work. My SIM card is PIN unlocked , and works fine in a different
alarm system. I have uploaded and tried different sketches but all fail on the 'Waiting for network..' I'm pretty sure
the network is strong enough to be found . I ordered a SIM card from a different provider in the hope that i can this
one working. Anyone has any idea what could be the cause?

 

thanks allot !

just for future reference, the problem was solved by checking the jumpers to choose between Serial and Serial1, and in case of Serial (using the INDIO unit) also disconnecting Serial from the RS485 port by moving the switch on the baseboard.
